Physical Science: Final Exam Study Guide

Front

On a distance – time graph, what does the slope represent?

Back

The slope represents speed.

Front

What is happening between segment C and D on a velocity vs time graph?

Back

The object is decelerating.

Front

What is Newton's first law also known as?

Back

Law of inertia.

Front

What does a curve on a distance vs time graph indicate?

Back

It indicates a change in speed.

Front

What do Free Body Diagrams represent?

Back

They represent the forces acting on an object.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).

Front

What does acceleration measure?

Back

Acceleration measures the rate of change of velocity.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What is the law of conservation of energy?

Back

The law states that energy cannot be created or destroyed, only transformed from one form to another.
